## What it is
An annotated copy of the JDK 1.8 source code with Chinese-language commentary explaining core classes like String, HashMap, ConcurrentHashMap, Thread, and ThreadPoolExecutor. It serves as a study resource for understanding Java internals and preparing for interviews.

## Use cases
- study how HashMap is implemented internally
- learn Java concurrency from Thread and ThreadPoolExecutor source
- understand ConcurrentHashMap internals
- prepare for Java backend interview questions
- read annotated JDK 1.8 source code with explanations

## When to choose
- you want line-by-line explanations of core JDK 1.8 classes
- you are preparing for Java interviews covering collections and concurrency
- you prefer Chinese-language commentary on Java internals

## When to avoid
- you need the official unmodified JDK source for building or compiling
- you need analysis of newer JDK versions beyond 1.8
- you need English-language explanations

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, documentation
- domain: programming-languages, tutorials, developer-tools
- platform: jvm, cross-platform
- tags: java, jdk8, source-code-analysis, annotated-source, concurrency, collections, interview-prep
